The function estimateRigidTransform is deprecated in version 4 and the could won't work. Would be cool if you fix it.

replace with m = cv2.estimateAffinePartial2D(prev_pts, curr_pts)[0]

fix with frame_out = cv2.resize(frame_out, (int(frame_out.shape[1]/2), int(frame_out.shape[0]/2)));

I tried the above and got this error:

Wonder how does this work on a live stream? because there is no an entire video worth of frames to compare
